Outline of Final Research Achievements

The aim of the present study was to elucidate the effect of working environment and exercise on the expression of “irisin,” a novel hormone shown to induce adipocyte browning. For this purpose, we investigated (1) the expression of irisin in workers exposed to a cold environment and (2) the comparison with the changes in the expression of irisin between participants who exercised from spring to summer and in participants who exercised from autumn to winter.
Our results showed higher expression of irisin in participants working in a cold environment than in a normal environment. Moreover, the expression of irisin appeared to increase in participants who exercised from autumn to winter, whereas there was no significant change in the expression of irisin in participants who exercised from spring to summer. Further study would be required in order to verify the present results due to the suspicion of cross reactivity of ELISA kit.
